The problem was introduced in commit eef3b57075
which was storing split commands inside keys themselves (for optimization).
This causes a problem when weechat.conf is reloaded, because all keys are
then deleted and created again, which removes the array of commands which
is currently used. And then it leads to a crash of WeeChat.
This commit reverts this behavior and the key commands are split when they
are executed.
